IMPROVEMENT IN EXPANDING DOUBLE-SHOVEL P'LOWS.

Specification forming part of Letters Patent No. 93,507, dated August10, 1869.

To all whom it may concern:

Be it known that I, EDWARD WIAED, of Louisville, in the county ofJefferson and State of Kentucky, have invented a new and ImprovedExpanding Double-Shovel Plow; and I do hereby declare that the followingis a full, clear, and exact description thereof, which will enableothers skilled in the art to make and use the same, reference being hadto the accompanying drawings, forming part of vthis specitcation, inwhich-- Figure 1 is a side view of my improved plow. Fig. 2 is a topview ofthe same.

ASimilar letters of reference indicate corresponding parts.

My invention has for its object to furnish an improved double-shovelplow, which shall be so constructed and arranged that the shovels may be adjusted to work at any desired distance apart or at any desiredpitch, as the circumstances of the casemay render desirable; and itconsistsin the construction and combination of the various parts ot' theplow, as hereinafter more fully described.

lA represents the plow-beam, and B the handles, about the constructionof which parts there is nothing new.v y

Y O are the plow-standards, which are made in about the form and mannershown in the drawingsthat is to say, they are made in the form-ot' thinplates having a laterally-projecting' ange upon each side of theirforward edges, to obtain the greatest amount of strength with thesmallest amount of metal, thus producing very light and at the same timevery strong standards.

. Upon the forward sides ofthe lower ends of the standards C are formedshoulders to rcceive the shovels D, each of which is secured in placeupon said standards by a single short bolt, as shown in Fig. 1.

-Upon the upper ends of the standards G are formed sockets, fitting uponthe hollow or tubular spindles E, where they are secured in place, whenadjusted, by means of set-screws, keys, or other well-known means. Thehollow spindles E are secured to the opposite sides ot' the. beam A byscrews or bolts passing through said beams and through ears formed uponthe inner ends of said spindles, as shown in Figs. 1 and 2. Thisconstruction allows the plows to be conveniently adjusted farther apartor closer together, as may be required.

F are brace-bars, the rear ends of which pass through a hole in thelower parts of the standards C, and are secured in place by screw-nuts,as shown in AFig.,1. The upper parts of the brace-rods F are slotted andrest in notches in the outer ends of the short postsor arms G. Thebrace-bars F have notches or teeth formed in the inner sides of theirforward ends, into which fits a ridge orv tooth formed inthe bottom ofthe notches in the ends of the posts or arms G, to prevent said bracesfrom slipping under the draft strain. secured to the posts G and to thebeam A by bolts which pass through the slot in the rods F, through theposts G, and through the beam A, as shown in Fig. 2.

It' desired, the braces F may be placed in the rear of the standards Cand their upper ends connected with the rear end of the beam A, whichshould be extended rearwardly to receive them. In this case the lowerends of the braces F may be formed solid with or att-ached to the lowerparts of thestandards C, as may be desired. The adjustable brace-bars Fenable the pitch of the plows tobe conveniently regulated as desired.

Having'thus described my invention, I claim as new and desire to secureby Letters Patent- 1. Adjnstablyconnecting the plow standards to theplow-beam by means of sockets formed in the upper ends of said'standards and the hollow spindles E, substantially as herein shown anddescribed, and for the purpose set forth. A

2. The plow-standards G, madeof a thin plate with a flange upon bothsides of its forward edge, substantially as herein shown and described,and for the purpose set forth.

3. The slotted brace rods F and posts or arms G, in combination with thestandards C and beam A, Whether said braces be placed in front or rearIof' said standards, substantially as herein shown and described, and forthe purpose set forth. Y, Y

4. An improved expanding double-shovel plow formed by the combination ofthe plows D, standards (J, hollowrspindlesE, bracebars F,` posts or-armsG, beam A, and handles B with each other, substantially as herein shownanddes'cribed, and for the purposes set t'orth.
